Application April 10, 1934, Serial No. 719,924 Renewed November 21, 1936 3 Claims.

This invention relates to a shingle, the general object of the invention being to provide a double lock for connecting the central portion of the lower edge of one shingle to the end portions of underlying shingles so as to prevent the shingles from being raised by the wind and to so form the shingles that a roof or the like can be easily and quickly covered by the shingles.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a fragmentary view showing a number of shingles placed on a roof or the like.

Figure 2 is a view of one of the shingles.

Figure 3 is a section on line 33 of Figure 1.

As shown in Figure 2, the shingle A is of considerable length with its upper edge straight and with its lower edge formed with a central straight part I and from each end of this straight part, said lower edge is cut or shaped to provide a series of steps 2, each of which is formed with a straight edge 2 and an oblique edge 2" which connects the straight edge of one step with the straight edge of the adjacent step. A recess 3 is formed at each end of the lower edge of the shingle and a small recess 4 is formed at one end of the shingle at the lower part thereof and a small tongue 5 is formed at the lower part of the other end of the shingle, the tongue of one shingle fitting in the recess 4 of the adjacent shingle of the row. The lower part of the central portion of the shingle is formed with a pair of right angle slits 6, the longitudinally extending portions 8' of which extend toward each other and terminate in the small holes 1. These slits form the oppositely extending tongues 8. The shingles are placed in rows, as shown in Figure l, with the central portions of the shingles of an upper row overlapping the abutting ends of the shingles of the under row, as shown in Figure 1, and with the two tongues 8 of an upper shingle passing under the end parts of a pair of under shingles adjacent the recesses 3 of said pair of under shingles, with that part of the upper shingle between the tongues bridging the opening formed by the two recesses 3 at the ad- J'acent ends of the pair of under shingles, as shown in Figure 3.

The nails are placed in the ends of the shingles adjacent the lower portions of the ends thereof, as shown at 9, with the nails passing through the upper shingles and through portions of the underlying shingles, this arrangement of nails firmly holding a pair of under shingles in place adjacent the lower portions of the ends thereof, upper shingle pass under the pair of under shingles.

Thus it will be seen that I have provided a shingle which can be easily put in place and which, when put in place, will be locked to a pair of shingles which are partly covered by the upper shingle, so that there is no danger of the wind raising the shingles out of position.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. 20

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:

1. A shingle of the class described comprising a body including a straight upper edge and straight end edges, with the lower edge having a centrally arranged straight portion and stepped portions diverging from the straight portion to the end edges, the lower central portion of the body having a pair of angles slit therein, the vertical portions of which pass through the straight lower edge and the horizontal parts of 35 which extend toward each other, said slits forming a pair of oppositely extending tongues the lower edges of which are formed by parts of said straight edge, the lower corners of the body being recessed and the tongues of one shingle being adapted to be placed under the abutting end portions of a pair of shingles overlapped by the first shingle, the tongues passing beneath the edges of the recesses of a subjacent shingle with the part between the tongue bridging the recesses.

2. An interlocking shingle comprising a body portion and a shingle simulating tab extending from said body portion, the lower edge of said tab being provided with slits extending inwardly therefrom and forming oppositely extending locking projections connected to the remainder of the tab by a relatively narrow neck portion, said body portion being provided with a recess adapted to receive the neck portion of an overedge thereof and forming oppositely extending locking projections connected to the remainder of the tab by a relatively narrow neck portion and adapted to be bent bodily from the plane of said shingle, the body portion of said shingle being provided with recesses of a. width sufiicient to receive the neck portion of a similar overlying shingle, the locking projections of the overlying shingle, when laid, underlapping the body portion of the underlying shingle.
